How to protect yourself from keyloggers

Sharing is caring!

The Nordea Group, a major Scandinavian bank reported an occurrence recently where over $ 1 million was stolen from the accounts of its clients. This was as a result of a mail sent to clients containing a malicious software, the body of the mail advised the customers to install the antispam software attached to the mail. A lot of customers fell for this wrong information and downloaded the software which later infected their computer with a Trojan virus called Haxdoor. Whenever the client visits the Nordea website to perform a transaction, the Trojan would pop up a window prompting the user to type in their personal details again. The user’s personal details would then be transferred to the author of the virus. This is made possible because of the keylogger embedded in the Trojan. According to Kaspersky, a Trojan is a malware that disguises itself as a legitimate software. The keylogger took records of the interactions between the client and the bank’s website, these records were then sent back to the manufacturer of the Trojan who would later make use of the records for criminal activities.
